摘　　要：综述了近年来图内外食品用塑料包装掺杂回收料的现状及鉴别手段，主要包括红外光谱分析．热性能分析．力学性能分析．色质联用分析．熔体流动速率及凝胶渗透色谱分析等，并对今后的研究工作提出了新的要求。The current status and identification methods of food-grade ptastic packaging doped with recycled plastics were reviewed. The infrared spectrum analysis, thermal properties analysis, mechanical properties analysis, chromatography-mass spectrometry analysis, melt mass-flow rate analysis and gel permeation chromatography analysis were emphatically introduced. At the end of the paper, a new requirement was put forward for the future research work.
